The problem is that the system crashes continously without an aparent reason when is managing an INVITE request from X-Lite. Openser is able to manage a couple of calls and after that it crashes.

I dont really know if the configuration script has something to do with this behaviour (I put the script attached).

The problem seems to be located in the avp.c function as per the following backtrace generated from a coredump. I put also below the logs. If you need more information, please let me know.

Thanks very much for your help.
